In Germany September 29, 1930 4 Claims. (01. 198-57) This invention relates to a discharger for tion in a perspective view. Fig. 8 shows in a bunkers with a lateral discharging slit from end longitudinal section, Fig. 9 in a cross section ac-- to end at its base. The hopper bottom closure cording to line x-a: of Fig. 8, but on an enbeing formed by a conveyor belt upon which the larged scale, another manner of carrying my inloose goods leaving the slit are heaped. vention into efiect.

The chief feature of this invention consists of The section of the bunker according to Fig. 3 the one side wall of the bunker opposite to the makes it clear that the flaps or chutes of the bunker slit being formed in such a manner side wall 1 of the bunker extend down to the that a section through this side wall made conveyor belt 2 while the under edge of the other 10 above the conveyor belt in the plane of side or front wall 3 of the bunker leaves a slit the passing belt or near it will give an extending over the whole length of the bunker intersecting edge not as usual in form of for allowing the loose goods to leave the bunker a straight line in the ground plane but a broken and to heap upon the conveyor belt 2 forming one by preference in the form of a zig-zag or the bottom of the bunker. The side wall 1 at its 15 a waveline. According to this invention this bottom part is formed of flaps or chutes 4, 5, 6, side wall of the bunker is staggered or stepped 7, 8, Fig. 1, which are arranged at dillerent in the conveying direction at least in its lower angles of inclination, Fig. 3.

Contrary to known to be discharged, the ow P Of the Other devices at present in use a uniform sinking of Side Wall 3 0f the bu e can be adjusted in the surface of the goods is thus attained over he ght as ind d in 3 a d it can D the whole length of the bunker by very simple V dcd with plates adju tab e as regards their 35 and cheap means. Thereby it is made possible angle of inclination.

to discharge at the same time a complete train of While according to Fig. 3 the flaps or chutes self discharging wagons into a long bunker are arranged with difierent angles of inclination whereby very much time and work will be with regard to the conveyor belt, the section saved. of Fig. 4 shows that the same effect can be 40 In the accompanying drawings some examples obtained by staggering the flaps or chutes 4-8 of carrying out my invention are shown. parallel to one another.

In Figs. 1-3 the discharging device is shown, With regard to difierent sorts of goods and the conveyor belt being arranged in the ground also in order to be able to adjust the discharging plan parallel to the axis of the bunker.

Fig. 6 shows a top view as shown in Fig. 6 or inclined to the longitudinal of a discharging device in which the conveying axis of the slit. belt in the ground plan is arranged slantingly to In order that my invention may be better the longitudinal axis of the bunker. Fig. '7 understood an example of the arrangement is 55 shows the arrangement according to the invenshown in a perspective view in Fig. 'l.

For diminishing the width of the arrangement the conveyor belt 2 may be provided with only one side wall as is well known.

Figs. 8 and 9 show another manner of carrying my invention into effect. Two longitudinal side walls of the bunker, both of the same construction are placed in an inverted position on both sides. In the centre of the bunker and above the conveyor belt 21 a saddle-like and adjustable chute 22 is arranged so that on both sides of it the loose goods are heaped upon the conveyor belt which is free from ground pressure. By staggering the steps or offsets 23, 24 and 25 on both sides, both the longitudinal side walls of the bunkers slope in such a manner that the charging plane of the conveyor belt is enlarged in its moving direction. The saddle 22 may be adjustable both with regard to its width, to its inclination and to its height above the conveyor belt 21.

This arrangement has the advantage that while the uniform sinking of the surface of the goods and the capacity of the bunker are preserved the construction height of the bunker is diminished and thereby building costs are saved, or with the same construction height an enlargement of the useful capacity is obtained.-

Having thus described my invention I declare that what I claim is:

1. An automatic bunker discharger, comprising a hopper having a lateral discharging slit extending from end to end at its base, and a conveyor belt under said hopper and adapted to receive loose goods discharged from the slit in said hopper, and a downwardly inclined extension on the lower end of one side wall of said hopper terminating in close proximity to the upper surface of said belt and of a cross section at its lower end consisting of a series of offset portions.

2. An automatic bunker discharger, comprissaid hopper terminating in close proximity to the upper surface of said belt and staggered at its lower end to form steps projecting successively further over said belt oppositely to the direction of travel.

3. An automatic bunker discharger, comprising a hopper having a lateral discharging slit extending from end to end at its base, and a conveyor belt under said hopper and adapted to receive loose goods discharged from the slit in said hopper, a downwardly inclined extension on the lower end of one side wall of said hopper terminating in close proximity to the upper surface of said belt, and. composed of sections forming steps projecting successively further over said belt oppositely to the direction of travel, and means for adjusting said sections to vary the distance of projection of each succeeding section beyond its preceding section.

4. An automatic bunker discharger, comprising a hopper having a lateral discharging slit extending from end to end at its base, and a conveyor belt under said hopper and adapted to receive loose goods discharged from the slit 105 in said hopper, two downwardly inclined extensions on the two opposite side walls of said hopper, each extension being composed of sections projecting successively further over the belt in steps, the steps of the two extensions 1 projecting farthest over the belt being arranged at opposite ends of the slit, and a saddle-shaped two-way chute mounted in the end walls of said hopper intermediate said extensions adapted to direct the material onto said extensions,
